Darin,it's great what you did with the image.It's exactly where I was going! My teardrop is long,although it's what's trotted out alot in fluids books.The 2.5:1 is supposed to be the absolute minimum for form drag and skin friction.The tail is 1.78 times the diameter of the drop.From the photos you can see smoke separating early on the Kamm K-Car and even the Insight.Why GM did the Impact/EV-1 the way they did may have been a styling concession and to improve rear vision.In plan-view,the EV-1 is beautiful,with body taper beginning midway on the doors.
